ABB DAI04 Technical Documentation

Product

ABB DAI04 is a fully analog raw input module designed for industrial automation. This input module processes different analog signals and converts them into executable signal forms within the device for further processing and analysis, so that industrial processes can be properly monitored and controlled.

Technical Specifications

Input Channels

The ABB DAI04 input module contains 4 fully independent analog input channels, which can receive multiple analog signal sources at the same time, with excellent channel-to-channel data acquisition accuracy. Signal Type and Range: Supports voltage input in the range of 0 to 10V or 4 to 20mA to meet the output signal requirements of most industrial sensors. The voltage input accuracy is ± 0.1% and the current input accuracy is ± 0.2%, ensuring the accuracy and reliability of the collected data.

Resolution

The ABB DAI04 system has high resolution; the voltage signal reaches 12 bits and the current signal reaches 11 bits. Yes, it can even detect subtle changes in analog quantities and provide a fairly detailed data basis for industrial process control.

Sampling rate

ABB DAI04 can be actively set within a given rate, up to 1000 times/second, and can be optimized according to the frequency of data acquisition in different industrial applications. It can effectively adapt to dynamic processes with random evolution and relatively stable and static processes.

Functional characteristics

Signal conditioning and filtering

ABB DAI04 has a built-in signal conditioning circuit to amplify and filter the input analog signal, which can effectively pre-process and effectively eliminate noise and interference components in the signal, help to ensure the quality of the signal, and help to obtain stable and accurate data during the acquisition process.

Diagnostic function

ABB DAI04 has a self-diagnosis function throughout the system, which can track the working status of the module itself in real time, including the channel connection status, the over-range area of the input signal, and whether the internal signal is normal. Once any abnormality is detected, these faults will be promptly fed back to the control system through the indicator light or communication interface, which is very convenient for maintenance personnel who want to quickly identify and clear faults, thereby minimizing downtime.

Communication interface

ABB DAI04 host control system adopts standard communication interface mode, such as Profibus-DP, carries relevant communication protocols, realizes high-speed, stable and reliable data communication, and seamlessly integrates into the existing industrial automation network, and works with other equipment. 4. Installation and use Installation method: It adopts standard guide rail installation, which can be installed on the guide rail in the industrial control cabinet immediately, saving a lot of installation space and time, and facilitating seamless disassembly and maintenance of the module.

Wiring method

ABB DAI04 provides clear and easy-to-understand terminal identification, which is convenient for users to correctly connect the cables of the analog signal source. Pay attention to the cable specifications and shielding requirements when wiring to ensure the quality and stability of signal transmission.

Configuration and programming

According to the needs, you need to use programming software or host computer configuration tools to set module parameters, such as signal type selection, sampling rate setting, communication parameter configuration, etc., to ensure that the module meets the control requirements of specific industrial application scenarios.

Application fields

ABB DAI04 analog input module is widely used in automation control systems in power, chemical, petroleum, metallurgy, pharmaceutical, food and beverage and other industrial fields. It is used to collect analog signals (such as temperature, pressure, flow, etc.) output by various sensors, and provides an important data basis for monitoring, fine-tuning and optimization of industrial production processes, thereby improving production efficiency, ensuring product quality and reducing production costs. It occupies a very important and inevitable position in the process of industrial automation.
